SUNRPC: Bury "#ifdef IPV6" in svc_create_xprt()
Clean up: Bruce observed we have more or less common logic in each of svc_create_xprt()'s callers: the check to create an IPv6 RPC listener socket only if CONFIG_IPV6 is set. I'm about to add another case that does just the same. If we move the ifdefs into __svc_xpo_create(), then svc_create_xprt() call sites can get rid of the "#ifdef" ugliness, and can use the same logic with or without IPv6 support available in the kernel.
